About CCE

More than 40 faculty members in Caltech's Division of Chemistry and Chemical Engineering (CCE) work at the forefront of their fields to advance knowledge in the areas of chemistry, chemical engineering, and biochemistry and molecular biophysics. Our faculty work in close partnership with undergraduates, graduates, and postdoctoral scholars. Together they apply their most innovative ideas to our fundamental knowledge of chemical processes, thereby tackling some of chemistry's most complex problems.

CCE at a Glance

Chemistry and Chemical Engineering at Caltech have a long tradition of excellence. Alumnus and CCE chair for 22 years Linus Pauling revolutionized the field with his insights into the nature of the chemical bond (Nobel Prize in 1954) and essentially invented the field of chemical biology. Arnold Beckman (PhD '28) invented the pH meter and other revolutionary instruments that led to new discoveries in biochemistry and medicine and founded Beckman Instruments, the first electronic instrumentation company. Gordon Moore (PhD '54) founded the semiconductor chip-making company Intel and authored Moore's Law (which predicts that the number of transistors on an integrated circuit doubles every two years). Rudy Marcus (Nobel Prize in 1992) revolutionized the theory of the rates of chemical reactions, and Ahmed Zewail (Nobel Prize in 1999) pioneered femtochemistry, allowing real-time observation of reaction transition states. Bob Grubbs (Nobel Prize in 2005) enabled olefin metathesis to become a powerful synthetic tool with broad applications in the chemical industry and the pharmaceutical industry. John Seinfeld (Tyler Prize, 2012) carries on Caltech's pioneering role in studying air pollution, determining the physics and chemistry of atmospheric aerosols. Frances Arnold (Nobel Prize in 2018) developed directed evolution as a way to invent new, protein-catalyzed reactions that are greener and more efficient than conventional processes.
